Line a square pan with parchment paper, leaving an overhang to lift the brownies out later; set the pan aside.
In a large mixing bowl add 1 cup almond butter, 1/2 cup maple syrup, and 2/3 cup cocoa powder. Stir until fully combined and smooth, scraping the sides of the bowl as needed.
Transfer the mixture into the lined pan and press firmly and evenly into an even layer with a spatula or the back of a spoon.
Spread 1 cup chocolate frosting evenly over the pressed brownie layer. If the frosting is very stiff, stir it until spreadable or briefly soften it just enough to spread.
Refrigerate the pan for at least 30 minutes, until the brownie layer is firm.
Lift the set brownies from the pan using the parchment overhang, place on a cutting board, slice into squares, and serve.
